Abstract

A therapeutic method for enhancing an effect of treating tumor such as cancer wherein activated lymphocytes are administered within a definite period of time before or after the performance of photodynamic therapy (PDT). By administering activated lymphocytes in parallel to PDT, synergistic effects of the PDT and the administration of activated lymphocytes can be established. As a result, tumor such as gastric cancer can be remarkably efficiently reduced and destroyed. Moreover, an excellent therapeutic effect can be achieved on tumor showing no sensitivity to PDT alone. On the assumption of carrying out in parallel to PDT, the above therapeutic method of administering activated lymphocytes, which would not always impart cancer specificity, contributes to the destruction of tumor or improvement in the effect of preventing the enlargement thereof.

Tumor treatment method and PDT parallel-curing lymphocyte proliferation-processed K stem

The present invention relates to a therapeutic method for significantly improving the effect of tumor treatment such as cancer by photodynamic therapy (PDT), and to a proliferative-processed fB stem of lymphocytes for PDT concurrent therapy. In particular, the administration of activated lymphocytes within a certain period of time before and after PDT treatment can be used to cure cancer and other tumors! ] The present invention relates to a treatment method that can dramatically improve fruit. m

In addition to surgical resection and administration of anticancer drugs, tumors such as cancer are treated with lymphocytes or lasers. . Furthermore, in the case of administration of lymphocytes, lymphocytes derived from peripheral blood and the like can be expanded by the immobilized anti-CD3 antibody or interleukin 2, and the lymphocytes expanded thereby It has already been severely determined by the present inventor that it has a swelling effect (see JP-A-3-80076 ^^).

Regarding laser irradiation treatment, a photodynamic TTierBpy (hereinafter sometimes abbreviated simply as “PDT”) is administered as a photodynamic TTierBpy, and then a cancer-affinity photosensitizer is administered in advance, and a laser beam is applied to the cancer site. In recent years, it has gained the spotlight because it has the advantage that it can be used for surgery, even if it is not possible to perform surgical operations, because it has the advantage that it can be used for surgical operations. ing.

By the way, according to the occupational achievements so far, although the data showing the effect is small and there is some variation, the treatment with gastric cancer using this PDT cures to 5506 in early gastric cancer and 890/0 in early gastric cancer. However, in advanced gastric cancer, 2 cases were found in 2 cases in the early period, and 4 cases out of 5 cases were found in the latter period. ^ Cancer (1996): 23 No. 1 41 Page to page 46].

The transfer of the spleen of a mouse not immunized with cancer does not suppress the growth of the cancer β transplanted into the scid (severe combined ummunodeficient) mouse ¾ ^, whereas the mouse fl ^ Certain that the growth of cancer fibers transplanted into mice after photodynamic contraction can be suppressed [CANCER RESEARCH (1999), 59,1941 -1946] ₀ Furthermore, the effects of mouse movements | Cure »fruit It is generally well-known that the age of Sakagami is large and small.

However, the above uses activated lymphocytes alone as an anti-tumor activity, and the anti-tumor effect is not so high, and is not involved in tumors or swelling in PDT therapy. Absent. It is also considered to prepare lymphocytes so as to react specifically to cancer by testing for cancer specificity. However, 1) the preparation work is complicated, and 2) cancer is difficult to induce. 3) Fibers are not always obtained, and 3) Phosphorus / spheres with specificity cannot always be prepared even if prepared by the same operation. Has not been reached. In addition, PDT therapy is not always effective for the target cancer, as shown in the results of previous studies that have been edited. Disclosure of the invention

Therefore, the present invention is a method for treating a tumor in which activated lymphocytes are administered in parallel with the treatment of PDT (photodynamic) therapy. By administering activated lymphocytes at the same time as, or within a certain period of time before or after, PDT therapy, activated Rinno that does not necessarily confer cancer specificity can be rescued and rescued. The effect of cancer Μ Μ Μ 减减 ¾Λ ¾Λ ¾Λ ¾Λ significantly increased: ^: Μ.

It is recommended that PDT therapy is performed repeatedly. <Activated phosphorous cells are administered before and within 6 months after PDT therapy, and significant tumor treatment is expected. it can.

Activated lymphocytes used for PDT therapy can be grown or cultured with anti-CD3 antibody or interleukin-2.

The pits contained in the body fluid or tissue that were obtained from the 化 t-phosphorylated lymphocyte section were processed, and then proliferated or transformed in the processing section to prepare activated lymphocytes for PDT parallel treatment, which were stored and stored. Alternatively, it is possible to construct a proliferative-processed immune system of PDT-like lymphocytes that are transformed into PDT on page 辦. With this multiplication process processing system, activated lymphocytes are stored in a bet from the processing section of the preparation-processing industry based on an order from a ^ I person such as a medical institution that treats ¾tt-ized lymphocytes as a page. A rational system can be constructed. Good form to make invention

The specific contents of the present invention will be described below as an embodiment of the present invention. Lymphocytes activated with anti-CD3 antibody and interleukin 2 prepared in advance were treated with PDT-irradiation in the first treatment after PDT irrespective of whether they were not cancerous lymphocytes. It was found for the first time that it had an excellent effect on certain cancers, and the present invention was completed.

Specifically, the treatment is performed in parallel with the treatment with PDT therapy, and the tumor is not necessarily imparted with cancer specificity and was prepared by pre-proliferation and activation with anti-CD3 antibody or interleukin 2. By administering the spheres within a certain period of time before and after PDT therapy, the effective treatment of tumors such as cancer is achieved by the synergistic effect of PDT therapy and the Kago-Lymphoclast method, which is synergistic. Is like fid.

[Lymph ^ β painting

The phosphorus / sphere used here is a complicated crop prepared for cancer-specific separation as in the past, and is not necessarily imparted with cancer. In general, lymphatic alveoli can be separated from the periphery and easily approximated. As a method for peripheral plaques, らの is preferred, and the amount of blood collected at one time is 0.01 ml 10 Oml, and it is not particularly purified. However, in consideration of the physical burden of the donor, the trouble of viewing, and the operation of separating lymphocyte fibers, it is preferable that the volume be within ^ ffl of 5 ml to 50 ml of cereals, more preferably, 10 m to 20 ml. Good.

In this case, heparin or coagulation can be added to the suspended female so that coagulation of the female does not occur. Separation of the lymphocytes from the females collected above can also be performed by separation of well-known lymph, such as the non-inclination ISI heart method, using a commercially available lymphocyte separating agent. You can get it.

[Rin / ¾ «multiplication-Hodani]

Next, the proliferation culture of the obtained cells will be described. The proliferation of lymph-IMS of the present invention is mainly carried out mainly by an anti-CD3 antibody, and from the viewpoint of further increasing the growth rate, the culture medium is used for culture. It is preferable to use Inter-Kickin 2 for the first step. Therefore, in the case of the present HJfe case, it is assumed that growth culture and transformation are difficult under the combination of interleukin 2 and anti-CD3 antibody.

Specifically, for example, lymphocytes can be suspended in a culture medium containing interleukin-2, and the culture can be performed by injecting the cells into an anti-CD3 anti-solid phase. Furthermore, it is also possible to carry out the proliferation and mitigation of various mitogen growth factors and chemical factors. As the anti-CD3 antibody, any antibody capable of activating the proliferation and activation of lymphatic cells is not particularly restricted. The anti-CD3 antibody used to stimulate phosphorus / sphere cells can be purified from animals or Although it can be produced by cells, a commercially available OKT-3 antibody (manufactured by Osofamass "^ ical), which is excellent in terms of stability and cost, can be produced by ^ ffl.

The anti-CD3 antibody is preferably used as a solid phase from the viewpoint of the efficiency of lymphocyte proliferation and ease of operation. Examples of the syllable for immobilizing the antibody include culture of materials such as glass, polyurethane, polyolefin, and polystyrene. In this case, a commercially available sterilized »S« flask made of plastic can be used because of its easy availability, and its size can be increased.

Further, immobilization can be carried out by immobilizing the dilute anti-CD3 antibody i, for example, at a temperature of 4 ° C to 37 ° C for 2 to 24 hours. For the immobilization of the anti-CD3 antibody, it is preferable to dilute the anti-CD3 antibody to a concentration of 1 to 30 μgZml in raw WJSS such as sterilized TA ^ CO りん ® solution. After immobilization, it can be stored in a cold room or refrigerator (4 ° C) until use. At this age, it can be removed, and if there is room temperature, Dulbecco's phosphate crane can be a conflict.

In addition, commercially available interleukin 2 can be used, and it is preferable to use it so that the culture medium has a concentration of 1 to 2000 U / ml. In addition, interleukin 2 is dissolved in commonly used cell culture media such as water, physiology: ^ solution, dalbecco phosphate solution, RPMI-1640, DM £ M, IMDM, AIM-V, etc. Can be used. Once dissolved, it is preferable to store it in a refrigerator in order to prevent a decrease in activity.

The culture medium used in this case is not particularly limited as long as it is suitable for culturing lymphocytes.

It is not pitted, but can be shelved when amino acids, vitamins, nucleic acid bases, etc. are added to a culture solution derived from a living organism such as serum, or a balanced salt j solution], PI-1640, AI-V, DE, IMDM, etc. Is preferred and RPMI-1640 is particularly preferred. Further, a culture medium to which normal human blue is added is preferable because it has an increased effect. Commercially available media can be used for these media.

In addition, the culture can be performed according to a general method of BS ± 咅 0, for example, in a C02 incubator “^. In this case, the C02 concentration is preferably 1 to 10%, particularly preferably around 5 <½. As for the temperature, it is preferably 30 to 40 ° C, particularly 37.0 fiber.

(PDT fine

On the other hand, PDT therapy first silences cancer affinity (3t sensation 1 ^ 1), and then concentrates the drug in cancer tissues and normal tissues. When the difference between 48 and 72 hours has passed, the laser beam is illuminated Ji to cause the drug taken up by the cancer to generate in the tissue, and by using the nature of this ^, the cancer ^ Male power to make E Gakushima.

The laser used for PDT therapy is, for example, a conventional laser such as Hamamatsu's excimer dye laser, such as an excimer dye laser, but not necessarily a PS laser. Any laser-generating device that can use PDre, such as a laser, may be used.

These PDT-protected lasers have a low power of about 100% of that of laser-scalpels and low tumor affinities. It can be controlled and is suitable for intensive treatment of cancer lesions only.

In addition, during photodynamics such as laser irradiation, a photosensitizer is administered in advance, and this photosensitizer must be a photosensitizer that has a specific affinity for tumors. Such substances include, for example, Porphymer Sodium (PHE-name at the time of distribution of PHE-Photofurin) from Japan Distilled Rice ± ^, and so-called PDT, which has been generally fined so far and can be used. Any photo-sensitive material that can be used may be used.

(Administration of Hodani lymphocytes)

Regarding the administration of activated lymphocytes, it is desirable that the dose be within 6 months before and after the surgery, in order to correlate the effect with the PDTJ surgery, and in this case, PDTtfeiF 湔, It may be a single dose on the day of PDTfife surgery or after PDT surgery, but considering sex and effect, it is desirable to be separated from 1 to 10 times, and the higher the dose, the more In general, one to several doses are administered.

In this Hi¾ case, activated lymphocytes were administered five times, but the present invention is not limited to this. In addition, administration of activated lymphocytes is effective before or only after PDTfife surgery, or only on the day of PDTfig surgery, or after PDT surgery. Alternatively, multiple doses may be given before, on the day of, or after PDTfiS surgery.

In addition to a single PDT fe procedure and keratinocyte treatment, the combination of PD ¾ surgery and keratinocyte administration can be repeated several times. In the case of further repetition, the treatment may be performed using a PDT-operated worm or an activated lymphocyte-administered worm, or a combination of both. Further PDTfife surgery b

Or activated lymphocyte injections: When repeated after each other, in order to ensure their ^] properties, a period of 6 months after the removal of one of them is given before ^! It is necessary to perform it.

Processing of C fiber-commissioned)

Also its collected Rinno II. The ball can be processed or imported in response to the page, and can be used as a cell processing commission system that provides this to the pager. In other words, the fibers contained in the bodily fluids or males provided by the arrogant part were grown or activated in the processing part, and then lymphocytes for PD τ¾¾β¾ί combination were prepared. A PDT-combined phosphor ball and a processing system for processing these fibers, which are used to provide this or to be used in the page section, are such.

In addition, here, "the deemed page part j" usually includes a case where a person is a β-processed arrogant person composed of a doctor, a dentist, and various doctors or a patient or his / her home. Samples collected from page $-The processing part that performs processing such as proliferation or activation of cells in body fluid or tissue is collected from the Ifib fluid-body fluid or This includes cases where the culture or activation of cells is performed by a supplier. Further, the term “part that prepares a cryopreserved cell after processing” includes the case where # is used to freeze the cell.

This age, female part-processing part-remote part may be abducted individually, but they can also serve as each other. Therefore, the droop that has been grown or cultured in vitro by the first part is frozen in the processing part, or in the cell preservation part or in the page part of the cell that is a cell member: d¾ $ page; You can also. When the cell processing section freezes the cells, the frozen cells can be stored in the fine BSiJii section or the cell section can be kneeled.

Thus, the cell processing unit or the cell storage unit can transfer the conserved cells to the arrogant part (cell storage deserving person) in either a frozen state or an awake state. In addition, the prepared リン -phosphorylated Rinno spheres can be sterilized in an appropriate solution and sent to a medical institution or the like, which is a pager, using existing delivery means such as a courier service.

In this case, if the TO from the ¾ ^ section is made by electronic communication means such as e-mail or writing on the Internet homepage, the activation link for cancer recurrence prevention is activated.

As a commissioned system for processing of spheres and these cells, it is possible to provide simple activities and services and services. „

Activated lymphocytes supplied from the processing section or the storage section are mainly administered to gastric cancer patients as an enhancer of PDT therapy. However, the present invention is not limited to the administration of stomach cancer patients. In addition to this, liver cancer, uncancer, kidney, m, month! ^, Ovarian cancer, child, seizuru, precancer, It can also be used as a potentiator for PDT removal in leukemia, sarcoma, B¾B ^.

In the above example, it is assumed that the lymphocytes used are of autologous origin, that is, peripheral blood taken from the vein of a gastric cancer patient who has not obtained a reduction effect by PDT removal. As described above, in another HS case, there is no danger of causing GVHD (Graft versus Host Disease) immunity, and lymphocytes derived from another person, which is obtained by HLA (Human Leukocyte Antigen) of Iraton, is used. Was used as a population of lymphospheres proliferated with anti-CD3, and it was revealed that the impact-inhibitory effect of tumors and other cancers was higher than that of autologous ones. Separation of use of production it

As described in detail above, the invention of the present application is such that the administration of activated lymphocytes is performed in parallel with the tumor treatment by PDT therapy, and the synergistic action of the two does not necessarily impart cancer specificity. It is not only a complicated preparation H ^ F¾ for the induction of lymphoid disease, but it is easy to obtain lymphocytes that can be used as well as cancer, especially gastric cancer. Not only does it have a remarkable effect on the suppression of the reduction of each type of obstruction, but it also has an excellent effect on patients who do not have any effect especially on battlefield treatment after PDT removal.

In addition, as lymphospheres used in this case, GVHD immunity ^ E is not likely to cause bow I, and lymphocytes derived from another person, including H of Ichinori, are proliferated and activated with anti-CD3 antibody. When used as a lymphocyte population, a more excellent effect of destroying and suppressing cancers such as tumors can be obtained as compared to autologous lymphocyte populations.

In addition, the present invention can be applied not only to prescriptions applied to the human body, but also to animals such as dogs and cats if they can be treated with PDT, or to livestock such as pigs, pigs, sheep, and horses. In addition, the activated lymphocytes used in the present invention may be expanded and cultured with an anti-CD3 antibody or interleukin 2.
